N2  - Eleven peptides have been isolated from the skin glands of the &#8216;buzzing tree frog&#8217; Litoria electrica. The two most abundant peptides are tryptophyllin L 3.1 &#91;Phe Pro Trp Pro (NH2)&#93; and electrin 1 &#91;Phe Val Pro Ile Tyr Met (NH2)&#93;. These peptides show neither significant antimicrobial nor smooth muscle activity. Tryptophyllin L 3.1 is thought to be a neuromodulator or neurotransmitter, and it is similar in structure to the human endomorphins &#91;e.g. Tyr Pro Trp Phe (NH2)&#93; which act on the &#947;-receptor. Both Litoria electrica and the &#8216;red tree frog&#8217; Litoria rubella produce tryptophyllin peptides: it is considered that both species evolved from the same ancestor.
